Explanation:
For transfer of heat between any two substances or matter can be occurred by conduction or convection process.
Conduction is a process in which two objects of different temperature are placed in contact with each other. Therefore, heat transfers from hotter object to colder object until the temperature of both objects becomes equal.
For example, a metal spoon placed in a hot cup of tea.
Convection is a process in which a fluid generally liquid or gas is heated and denser material (colder) sinks at the bottom whereas less denser material (hotter) rises at the top. This causes conventional currents in the fluid.
For example, heating rice in a pot full of water.
Answer:
The answer to your question is 14.3 %
Explanation:
Data
volume of ethanol = 50 ml
volume of water = 300 ml
volume percent = ?
Formula
Percent by volume = (volume of solute/volume of solution) x 100
Volume of solute = 50 ml
volume of solution = 300 + 50 = 350
Substitution
Percent by volume = (50/350) x 100
Simplification and result
Percent by volume = 14.3 %
Explanation:
I believe the most massive element that is naturally occurring on Earth is uranium (U), which has a nucleus of 92 protons
Answer:
moles of water in 1 ml = 1/18 mol.
take 1 ml and calculate it by 30
1 ml x 30= 30 ml
